DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

Certain exemplary embodiments of the present invention will now be described in greater detail with reference to the accompanying drawings.

FIG. 1A is a view illustrating a broadcast receiving system according to an exemplary embodiment of the present invention. Referring to FIG. 1A, a broadcast receiving system comprises a DTV 100 as a broadcast receiving apparatus and a remote control (remote control apparatus) 200 as a user input apparatus.

The DTV 100 provides a user with a broadcast received over wire or wirelessly, through a display D. Additionally, the DTV 100 may provide a user with an external input received from an external apparatus which is connected over wire or wirelessly, through the display D, and may also provide a user with a broadcast by reproducing a file, such as a moving image file, a still image file, and a music file, stored in a built-in storage media.

The remote control 200 sends information on the manipulation of the user to the DTV 100, and the DTV 100 operates according to the received information. Although the remote control 200 of FIG. 1A includes a plurality of keys, the remote control 200 may include either one or two keys as occasion demands. A plurality of keys are provided on the top side of the remote control 200, but the plurality of keys may be provided on the other sides such as the left or right side, or the bottom.

As indicated by dotted arrows in FIG. 1A, the face of the remote control 200 may be moved in a space by the user in an upwards or downwards direction, or to the left or right, or in a direction combining two of these directions, such as an upper-leftwards direction. That is, the face of the remote control 200 may be moved in any direction.

For example, the face of the remote control 200 may be moved while drawing a locus on a virtual plane (VP) which is in a parallel relation with a screen of the display D. FIG. 1B is a view illustrating a case in which the face of the remote control 200 is moved to the left direction while drawing a locus on a virtual plane which is in a parallel relation with the screen of the display D by the user.

The VP may not be in a complete parallel relation with the screen of the display D, and may not be a complete plane. That is, it is practically impossible for the movement of the face of the remote control 200 by the user to be on a complete plane and in a complete parallel relation with the screen of the display D.

Accordingly, the present invention is applicable to the case in which the face of the remote control 200 moves on an incomplete plane and in an incomplete parallel relation with the screen of the display D.

A user may move the face of the remote control 200 by turning only the user's wrist while the user's arm holding the remote control 200 is fixed.

If only the user's wrist moves in an upwards or downwards direction, or to the left or right, or in a direction combining these, such as an upper leftward direction, the face of the remote control 200 may be moved upwards, downwards, or to the left or right, or in a direction combining these, such as an upper leftwards direction while drawing a curved locus on a virtual hemisphere surface. FIG. 1C is a view illustrating the case in which the face of the remote control 200 is moved to the left by a user while drawing a curved locus on a virtual hemisphere surface.

The virtual hemisphere surface, on which the face of the remote control 200 is moved by rotation of the user's wrist, may be a mathematically incomplete hemisphere surface. That is, it is practically impossible for the face of the remote control 200 to be moved by rotating the user's wrist while drawing a locus on a mathematically complete hemisphere surface.

Accordingly, the present invention may be applicable to the case in which the face of the remote control 200 moves not on a mathematically complete hemisphere but an incomplete hemisphere surface while drawing a curved locus.

That is, the pointer P displayed on the display D may be moved by the user spatially moving the remote control 200. The spatial movement of the face of the remote control 200 is distinguished from the movement of a mouse for a personal computer (PC) which is moved over a surface.

When the face of the remote control 200 is moved in a space, the pointer P displayed on the display D moves in the same direction as the face of the remote control 200. For example, i) if a user moves the face of the remote control 200 upwards within a space, the pointer P may move upwards, and ii) if the user moves the face of the remote control 200 to the upper-left in a space, the pointer P may move to the upper-left.

Hereinafter, the TV 100 and the remote control 200 illustrated in FIG. 1 will be explained in detail with reference to FIG. 2. FIG. 2 is a block diagram of the TV 100 and the remote control 200 of in FIG. 1.

Referring to FIG. 2, the remote control 200 includes a movement sensor 210, a transmitting unit 220, a remote control unit 230, and a key input unit 240.

The movement sensor 210 senses the movement of the face of the remote control 200 by the user, and sends the result of sensing to the remote control unit 230 which will be explained in detail below. An exemplary implementation may use a biaxial gyro sensor as the movement sensor 210.

The key input unit 240 may include a power key, a channel key, a volume key, and a select key.

The remote control unit 230 transmits information on the movement such as moving direction, moving distance, which is obtained from the sensing result transmitted from the movement sensor 210, to the TV 100 via the transmitting unit 220. The remote control unit 230 also sends the TV 100 information about keys input by the user through the transmitting unit 220.

Referring to FIG. 2, the TV 100 includes a broadcast receiver 110, a broadcast processor 120, a Graphic User Interface (GUI) generator 130, an output unit 140, a controller 150, and a receiver 160.

The broadcast receiver 110 tunes to one of the broadcast channels and demodulates a broadcast signal. The broadcast processor 120 executes broadcast signal processing such as decoding, or scaling of the broadcast signal provided from the broadcast channel tuned by broadcast receiver 110.

The GUI generator 130 generates a GUI to display on the display D, and combines the GUI with the broadcast output from the broadcast processor 120.

The output unit 140 may display broadcast combining the GUI output from the GUI generator 130 on the display D, or output to an external display such as external TV connected through an external output terminal (not shown).

The controller 150 controls the overall operation of the TV according to the user's manipulation including movement of the face of the remote control 200, or a key input, which is transmitted from the remote control 200 via the receiver 160. More specifically, the controller 150 controls the tuning of the broadcast receiver 110, and the generation of the GUI by the GUI generator 130.

The controller 150 controls the GUI generator 130 to provide GUI for selecting a broadcast channel having an operable keypad usable with a pointer P, and controls the broadcast receiver 110 to tune to a broadcast channel selected by the user using the GUI for selecting a broadcast channel, which will be described in detail below referring to FIG. 3. FIG. 3 is a flowchart illustrating a method for providing GUI for selecting a broadcast channel in accordance with an exemplary embodiment of the present invention.

Referring to FIG. 3, if a broadcast channel list display command is input (S310-Y), the controller 150 controls such that a broadcast channel list and a pointer P are displayed on the display D (S315).

The broadcast channel list display commend at S310 may be input by pressing the channel key on the key input unit 240.

To execute S315, the controller 150 controls the GUI generator 130 to combine the broadcast channel list and the pointer P with a broadcast to be displayed on the display D.

FIG. 4A illustrates an example of the display D displaying the broadcast channel list 410 and the pointer P combined at S315. Referring to FIG. 4A, a keypad icon 420 and a preferred channel icon 430 are displayed at the bottom of the broadcast channel list 410.

The keypad icon 420 is used to input a command for calling for the keypad onto the display D, and the preferred channel icon 430 is used to input a command for calling for a preferred broadcast channel list onto the display D.

If the keypad icon 420 is selected by the pointer P (S320-Y), the controller 150 controls such that the keypad is displayed on the display D (S325).

The selection at S320 is executed by moving the face of the remote control 200 on the VP to move the pointer P to point the keypad icon 420, and then by pressing the select key on the key input unit 240 of the remote control 200.

To execute process S325, the controller 150 controls the GUI generator 130 to generate a keypad and combine the generated keypad with the broadcast displayed on the display D.

FIG. 4B illustrates an example of the display D displaying the keypad 440 combined at S325 at the right of the broadcast channel list 410. Referring to FIG. 4B, the keypad 440 includes number keys (0˜9) to input numbers, a subdividing key (-) to divide channel numbers into a major broadcast channel number and a minor broadcast channel number, and an input completion key (OK) to confirm an input completion. The keys may be selected by using the pointer P.

Referring to FIG. 4B, an input window 450 is displayed at the top of the keypad 440. The input window 450 displays the numbers (0˜9) and the subdividing (-) as selected by the pointer P on the keypad 440. For example, number “16” is displayed on the input window 450 in FIG. 4B. It means that the user selects number keys “1” and “6” by using the keypad 440 and the pointer P.

According to the number key input by the user using the keypad 440 and the pointer P, the broadcast channels being listed in the broadcast channel list 410 may be changed. More specifically, all the broadcast channels including the number input by using the keypad 440 and the pointer P may be displayed in the broadcast channel list. For example, referring to FIG. 4C, if the user selects the number key “3” by using the keypad 440 and the pointer P, all the broadcast channels beginning with “3” may be listed in the broadcast list 410. In another example, if the user selects the number key “3” by using the keypad 440 and the pointer P, all the broadcast channels such as 13, 311, 93 including “3” may be listed in the broadcast list 410.

If the broadcast channel is input by using the keypad 440 and the pointer P displayed at S325 (S330), the controller 150 controls the broadcast receiver 110 such that the input broadcast channel is tuned (S335). The broadcast provided from the broadcast channel tuned at S335 is displayed on the display D.

The broadcast channel input at S330 is terminated i) if the input completion key (OK) on the keypad 440 is selected by the pointer P, or ii) if no key is selected by the pointer P for a reference time (for example, for 2 seconds), after inputting the broadcast channel by using the keypad 440 and the pointer P.

Meanwhile, if the preferred channel icon 430 is selected by the pointer P after S315 (S320-N and S340-Y), the controller 150 controls such that the preferred channel list is displayed on the display D (S345).

The selection at S340 is executed by moving the face of the remote control 200 on the VP to move the pointer P to point the preferred channel icon 430, and then by pressing the select key on the key input unit 240 of the remote control 200.

To execute S345, the controller 150 controls the GUI generator 130 to generate a preferred broadcast channel list and combine the generated preferred broadcast channel list with a broadcast to be displayed on the display D.

FIG. 4D illustrates an example of the display D listing a preferred broadcast channel list 460 combined at S345 at the right of the broadcast channel list 410. Referring to FIG. 4D, the preferred broadcast channels are listed on the preferred broadcast channel list 460, and the user may select one of the preferred broadcast channels listed by using the pointer P.

If one of the preferred broadcast channels listed on the preferred broadcast channel list displayed at S345 is selected by the pointer (S350-Y), the controller 150 controls the broadcast receiver 110 such that the selected preferred broadcast channel is tuned (S335). The broadcast provided from broadcast channel tuned at S335 is displayed on the display D.

Meanwhile, if one of the broadcast channels listed on the broadcast channel list 410 displayed at S315 is selected by the pointer (S320-N, S340-N, and S355-Y), the controller 150 controls the broadcast receiver 110 such that the selected broadcast channel is tuned (S335). The broadcast provided from the broadcast channel tuned at S335 is displayed on the display D.

Meanwhile, if a keypad display command is input (S310-N and D360-Y) when the broadcast channel list 410 is not displayed on the display D, the controller 150 controls such that the keypad 440 and the pointer P are displayed on the display D (S365).

The keypad display command at S360 may be input by double-clicking the channel key on the key input unit 240 of the remote control 200 within one second.

To execute the S365, the controller 150 controls the GUI generator 130 to combine the keypad 440 and the pointer P with a broadcast to be displayed on the display D.

FIG. 4E illustrates an example of the display D displaying the keypad 440 and the pointer P combined at S365. The GUI for selecting channel displayed on the display D illustrated in FIG. 4E has a different form from GUI for selecting channel on the display D illustrated in FIG. 4B, that is, the broadcast channel list 410 is not displayed in FIG. 4E.

If the broadcast channel is input by using the keypad 440 and the pointer P displayed at S365 (S370-Y), the controller 150 controls the broadcast receiver 110 to tune to the input broadcast channel (S335). Accordingly, the broadcast provided from the broadcast channel tuned at S335 is displayed on the display D.

As described above, the process of tuning to a broadcast channel selected through GUI for selecting a broadcast channel having an operable keypad usable with the pointer is explained with exemplary embodiments of the present invention.

According to the exemplary embodiments of the present invention, the broadcast channel may be selected through not only a keypad operable with a pointer, but also a preferred broadcast channel list or a broadcast channel list operable with a pointer.

Although the exemplary embodiments have described the TV as an example of the broadcast receiving apparatus, the broadcast receiving apparatus may be implemented as a set top box (STB), a digital multimedia broadcast (DMB) receiving apparatus, and a portable apparatus with a built-in module for receiving broadcast such as a mobile phone with a built in module for receiving DMB. In the case of the portable apparatus, a pointer may be moved by using a touch pad instead of a remote control.

The pointer and the keypad forming a GUI for selecting a broadcast channel may be embodied in the form as illustrated in FIG. 4B, but different forms are possible. Keys on the keypad may also be configured in a different form from FIG. 4B, according to alternative examples of the present invention.

In the exemplary embodiments, when the broadcast channel list is not displayed on the display, the command to display the keypad is input by double-clicking the channel key on the remote control within one second. Herein, “one second” may be changed as occasion demands.

Instead of double-clicking the certain key on the remote control within the reference time, another examples such as pressing once the certain key on the remote control, are possible to cause the keypad to display while the broadcast channel list is not displayed on the display.

Another exemplary embodiment of the present invention is described with reference to the FIGS. 5 and 6.

Referring to FIG. 5, the broadcast receiving apparatus according to another exemplary embodiment of the present invention includes a broadcast receiver 510, a GUI generator 520, and a controller 530.

The broadcast receiver 510 tunes to a broadcast channel, the GUI generator 520 generates a GUI and combines the generated GUI with a image displayed, and the controller 530 controls the GUI generator 520 to generate a pointer to be moved by manipulation of the user on a remote control, and a keypad having selectable keys by the pointer, and to combine the generated pointer and keypad with the displayed image. The controller 530 controls the broadcast receiver 510 to tune to a broadcast channel input by using the keypad and the pointer.

According to the method for providing the GUI for selecting the broadcast channel illustrated in FIG. 6, the controller 530 controls the GUI generator 520 to generate a pointer to be moved by manipulation of the user on a remote control, and a keypad having selectable keys by the pointer and to combine the generated pointer and keypad with the displayed image (S610). The controller 530 controls the broadcast receiver 510 to tune to a broadcast channel input by using the keypad and the pointer (S620).

Accordingly, a GUI for selecting a broadcast channel having an operable keypad with a pointer may be provided.

According to the exemplary embodiments of the present invention as described above, the broadcast channel is selected with a keypad usable with a pointer. Accordingly, the user is able to input a preferred broadcast channel without using the number keys, so the number keys may be omitted in the remote control apparatus. As a result, miniaturization of the remote control apparatus is possible.

Further, the foregoing exemplary embodiments and advantages are merely exemplary and are not to be construed as limiting the present invention. The present teaching can be readily applied to other types of apparatuses.
